It stood there in the field where it had been sent, standing naked in a perfectly semi-spherical crater that still smoked and flashes of lightning were just beginning to fade away.
It had no idea about sex, but its appearance was all male. It looked human, but inside it was a hyperalloy combat chassis - micro processor-controlled, fully armored. Very tough. But outside, it's living human tissue - flesh, skin, hair, blood, grown for the cyborgs...
And it had drawn attention to itself. All around the field shuffling creatures, smelling meat, shambled towards him, reaching out towards him. He did a combat scan, cataloged them all, evaluated no threat, and turned to leave. Suddenly, a thin smiling man appeared in front of him and smiled, showing sharp, sharp teeth. It turned its head like a dog, and went for his throat in a flash.
The Terminator stopped him, with a hand to the chest, then pressed in and ripped its heart out. It burst out a mouthful of saliva into the Terminator's face, and the Terminator slapped its head off. He noticed three more things just like this one, standing off at fifty yards, and noticing they were noticed, they turned to run. Bounding at them, he slapped their heads off as well, and stood there and ran a full diagnostic.
He never felt anything, and now he felt...different. He bent over at the waist, as a wave of nausea took him, and if he could know fear, he would have felt it now. His vision, always acute, had darkened, but he could see further, and with more acuity than his design specifications had allowed for. He could see the glow that comes from living things, the trees were pillars of light.
And then he felt something bite into his arm, and chew for a bit. He slapped its head off, and its body lay on the ground, its feet churning it into a circle, around, and round. He looked around, and found he was becoming surrounded. He could have destroyed all of them easily, but he would be doing it everywhere he went. He jumped backwards up to the lower branch of of a tree to compute.
His stomach contracted again, and suddenly he understood what these shuffling beasts wanted...meat. He never ate, unless he was on an infiltration mission, but he wanted to tear apart a human with his teeth and feast on their flesh. He wanted to chase them down and tear their throats out and drink and bathe in their blood. Suddenly, he realized that he had been exposed to two unique viruses, and even as they ravaged his meat-shell, Skynet could weaponize them, and his Mission Directive changed: Secure The Viruses.
So he tore branches off of the tree, and tossed them down to make a bonfire pile below. Then he tore his chest open, and opened a compartment and pulled out a phosphorous grenade, popped the top and pressed the button, and then dropped it into the woodpile he had made. He checked the temperature to see if it exceeded his design specifications, which it did not, so he jumped into the middle of it.
His meat began to bubble, and slough away. He used his hands where he could see, and then sat down in the fire to get every piece. The strange vision went away, then the hungers, and finally, he stepped out of the fire, a gleaming, steaming vision of death. The shuffling dead lost all interest, and turned away, off to look for food.
He opened another compartment in his chest, and brought out a vial. He leapt through the air and came down with the needled vial and stuck it into the base of the spine of the last of the shuffling dead until the tube filled with black blood.
Then he scanned the field, and there they were, three more of the thin men with sharp teeth. He was on them before they could think to run, and held one down with a hand in its back, while the others fled.
Remembering its discomfort, the big silver man that was not a man, crushed the creature's head unto the ground, and ripped out its heart.
With the two vials secure in its chest cavity, it kept going until it found a high cave, and went in. It set its timer to send out a signal to Skynet twenty years in the future, set its defense options, then sat down on a rock and powered down. Its red eyes flickered a bit, then went out.
